in gold they are not available for good money directly from Sodastream, you would unfortunately have to buy the whole package again, incomprehensible.

yes, Galaxus offers the SodaStream Fuse Metal DWS. However, I bought the simpler Fuse bottles, which fit perfectly.

We use bottles that fit: SodaStream Fuse bottles
I haven't found any gold ones at Galaxus at the moment, but I'm sure they're available somewhere :)
